Application in BMW models with M47N / M47N2 engines

The presented vacuum pipe has been designed to work with BMW diesel units from the M47N and M47N2 family, used in, among others, the E46, E60, E61, E87, E90, and E91 series. It is responsible for the precise delivery of vacuum to control elements, which is crucial for the proper operation of systems such as engine accessory control or selected auxiliary modules. Maintaining the original routing of the hoses reduces the risk of leaks and malfunctions of components dependent on vacuum.

Technical and functional characteristics

The pipe belongs to the group of components referred to as Hoses, lines, and pipes, responsible for transporting working media in the engine compartment. In the case of a vacuum system, it is crucial to maintain the appropriate stiffness and tightness of the hose to avoid pressure drops and disturbances in the operation of controlled components. The original design of the hose ensures:

• a tailored path in the engine compartment, minimizing stress and friction against other elements,
• the appropriate internal diameter for stable vacuum flow,
• compatibility with factory ports and connectors in a given type of engine unit.

Thanks to this, the installation is orderly, and the vacuum system maintains parameters close to factory specifications.

Original origin and replacement numbers

The item comes from the BMW line and is an OEM class part, which means compliance with the vehicle manufacturer's factory standards. The part has a dedicated catalog number and assigned interchangeable numbers, which facilitates the selection of the correct hose for a specific engine version and model year. In practice, this allows for trouble-free identification of the component in service catalogs and verification of compatibility with your specific vehicle.

Condition and suitability for further use

The vacuum hose is offered in used condition, which allows for an economical replacement of the element while maintaining the manufacturer's original specifications. For many users, this is a reasonable compromise between repair costs and maintaining the factory design of the system. A properly selected hose helps to reduce problems related to leaks, unstable accessory operation, or errors resulting from incorrect pressure in the vacuum system.

Support with selection and system expansion
